At present, the security inspection of subway, high-speed rail and aircraft is generally divided into human security inspection and object security inspection. Generally, the human security inspection adopts the contraband security inspection door, and the security inspection of personal belongings generally adopts the security inspection machine. After the tested person passes through the security inspection door, the staff next to the door will scan the tested person from top to bottom with a handheld metal detector to avoid any omission.
After layers of security check, many people have questions about this. Will the things we carry on our bodies be displayed on the display screen of the door body when we pass the security check? Will our bodies also be scanned and displayed on the staff's computer, and the staff will see our "privacy"?
First of all, we need to know or understand one thing, that is, what is the detection principle of the security gate? How does it check people? According to Xiaobian, the current principle of intelligent contraband detection door is a principle called eddy current detection and electromagnetic induction. The strength of this detection principle is that it can eliminate the separation of daily necessities and contraband, that is to say, it can intelligently eliminate the mobile phones, watches, keys Contraband on the inspected personnel (such as aluminum cans, aluminum tubes and other contraband) is detected on the basis of metal articles such as belt buckles that are carried around daily
This intelligent contraband detection door can display the text and image of the detected categories of metal objects through the touch screen on the host, such as tools, dangerous goods, tin cans, aluminum cans, mobile phones, watches, etc. if the detected person carries contraband, the detection door will give a real-time sound and light alarm, and the virtual human location will display the hiding location of the contraband, Pictures and words shall be used to inform the shape and material of the tested contraband.
In addition, the touch screen of the door body can also display the number of people passing through, the number of alarm people, the category of alarm items, the virtual human location of alarm items, the detection date, the detection time, etc., and the displayed information content can be customized according to customer requirements.
Therefore, the contraband detection door will not reveal our personal privacy. If we really carry the contraband and are detected by the detection door, we usually only display the type of the contraband and the location of the body on the door. Moreover, the human location is still a virtual portrait, which will not reveal any of our secrets at all.
